INSTRUMENTATION BATTERY TESTING

Continued instrumentation battery failure on the N.S. Savannah led to tests to determine the actual battery characteristics, and to evaluate these characteristics with respect to ship's specifications and technical adequacy. During plant operation prior to core loading, battery capacity must be adequate to supply the AC bus during switching transients on the ship's bus and at other times when the main bus is dead. Following core loading and prior to final ship delivery, battery capacity must be adequate to supply the instrument bus during switching transients experienced on the main bus. It must also supply the AC bus for a sufficient time following complete loss of ship's power to ensure that the reactor is safely subcritical and that the existence of concurrently arising radiation problems is known. A simplified diagram of the instrumentation bus is provided.
